v The oibjectof.

Y y invention isnto improve v`theconstructionpoli a loom r` shuttle,whereby tliefshuttleisipro r,ided with asimple, durable l .handthreading'.A device adaptedfito facilitate thc threading :of tthe iMyinventioi'i consistsin thepeculiar-aiid nevel?y construction ofthedelivery end of a loom 'shuttles-andi mechanisml for threadingtheshuttle by hand, as will be more fully set forth hereinafter andclaimed.

ln the drawings., a indicates the thread delivery end of a loom shuttle,t the bobbin, c the bobbin cavity, d the throat, e a cavity at 46 thevend of the throatd extending from the top of the shuttle downward tothi` center of the shuttle and. opening into the throat d, f a

-The inner threadin member n is formed of wie-.c shaped to'havet cstraight shank 7 and 1 thepointed end ,8 bent at riglitangles to theshank, as shown in Fig; 5. The shank 7 "is bottom of the cavity e andthe pointed end 8 forced into the Wedge-shaped projectionk, as

shown in Figs. Sand 4. The guide eye member o' is formed from wireshaped to have the .straight shanky Q'and the circular coiled end Ghentat right angles to the shank and havingxthe reduced vend'll slightlyclearing the basev of the coil and forming an opening 12 between the end11 and the baseof the' coil,

as shown in Figs. 2 and 6. The shank 9.i s

driven into the small transverse hole m in a position to bring vthecoiled end' 10 into vthe circular depression f, as shown in Figs. 2- and4.

ln threading the shuttle the thread is first e and depressed into thecavity e, then carried into andthrough the slit h into the slit t, and

from which'point it iscarried under the reduced end 11 and throu h theopening 12 into the coiled end 10 oft e guide eye member o which formsthe delivery eye of the shuttle. The thread 'now runs from the bobbin b'around the inner threading member 'a vthrough the slit 'i and hole g andout through the coiled end 1() of the guide eye member o. The thread isnow prevented from returning by the lower edge of the circulardepression f holding the thread away from the opening 7c -in the guideeye member o.

I claim as new and desire to secure by Letters Patent 1. A shuttle bodyhaving a cavity' at the end of the throat, a transverse holeextending inand from the side to the cavity, a thread passage in the form of a slitextending from the top and side downward at an angle and then backlongitudinally into thecavity and transverse hole, an inner threadingmember having a straight shank driven -downward into the bottom of thecavityand a pointed end forced into vthe wall ofthe cavity, and a guidee. e member in the transverse hole in the s uttle.

pulled from the bobbin bever. the cavity,`

then through the slit iinto the depression Q7 driven downward into thesmall hole-Z in the' Having thus fully described my invention,

2. A shuttle body having a cavity at the end ofthe throat extending fromthe top of the shuttle downward, a transverse hole extending from theside of the shuttle inwardly to the cavity, a thread assage inthe formof a slit extending from t e top and side downward at an angle towardthe point of the shuttle and into the cavity and: then backlongitudinally toward and into 'the cavity and transvers e hole, forminga wedge-shaped projection'in the wall of the cavity, an innerthreading-member having' a straight shank j driven downward into thebottom of the cavity, and-fa pointed end bent at right angles and forcedinto the wedge-shaped projec-v tion, and a guide eye member inthetransverse hole in the shuttle.

3. A shuttle body having a cavity at the 1 end of the lthroat extendingfrom the top of tle and then back longitudlnall toward and into thecavity, the recess and t e transverse hole, forming a wedge-shapedprojectionin the wall`of the cavity, an inner threading member having astraight shank driven into the bottom of the cavity and a pointed endbent a't right angles and forced into the wedge-shaped proJection, and aguide eye member having a straight .shank anda coiled end bent at rightan lesand` secured by driving the shank into t e transverse hole in theshuttle in a vposition to bring the coiled end into the .circular recessin the side of the'v shuttle. y

4. The combination with. a shuttle body having a'bobbin cavity c, Vathroat d, a cavity e at the end of the throat d, a circular recess f inthe side, a transverse hole' g extending from the recess f the cavity e,an inclined slit h extending from the top and side downward 'toward theoint of the shutt1e"and into the cavity e, a ongitudinal slit 'iextendingl in from the side of the shuttle to the cavity e andintersecting the slit hand the hole g and forming with the slit h awedge-shaped projection k, a small oil-center vertical holeZ extendingdownward froml the bottom of the1 cavity e, and a small transverse holem ex-` tending inward from the recess f under ythe hole g, of an innerthreading member n hav-- ing the yshank 7 adapted to be driven into thevertical hole l anda pointed end 8 bentv at right angles andadapted tobe forced into the wedge-shaped projection 7c and a guide.. eye member ohaving the shank 9 adapted to be driven into the transverse. hole m, anda coiled end 10 bent at right angles tothe shank and having the reducedend 1 1 and th;

opening 12 and adatedto enter the recessf in the side of the s uttle andform the d e`` livery eye of the shuttle, as described.

In testimony whereof I have l signed'my name to this specification inthe two subscribing witnesses.
